Electrocatalytic Surfaces Using Bulk Metallic Glass Nanostructures

Osuji, Schroers, and Taylor
Metallic glass nanostructures provide a new platform for electrocatalytic applications. Several surface modification strategies that remove or add metal species (top images) improve the catalytic activity of metallic glass nanostructures. These strategies were demonstrated for three key electrocatalytic reactions important for renewable energy.

Templating Nanomaterials from Defects in Liquid Crystals

Nicholas L. Abbott, Juan J. de Pablo*, University of Wisconsin-Madison, *University of Chicago
Defects in liquid crystals can function as nanoscopic molds for assembling molecules
New semiconductor alloys have been developed that have band gap tunability allowing materials to be tailor-made to the application despite the limits imposed by nature. One such alloy is GaAs(1-x-y)P(x)Sb(y) with wide bandgap tunability.

Efficient and uniform doping of zinc oxide nanocrystals via plasma synthesis

Eray Aydil, Uwe Kortshagen, Andre Mkhoyan
In solution-based synthesis, often doping efficiencies are low and dopants are excluded from the nanocrystals’ central cores. The research team developed a fundamentally different plasma-based process for synthesizing aluminum-doped zinc oxide nanocrystals.
Understanding the transport of electrons in films of touching nanocrystals is of central importance for their future use in printed electronic devices such as light emitting diodes, solar cells, or transistors. The research team developed a new theory that describes the transition of the electron conduction in doped nanocrystal films from a semiconducting to a metallic behavior.
